Detailed explanation-1: -The information in RNA, although copied into another chemical form, is still written in essentially the same language as it is in DNA-the language of a nucleotide sequence. Hence the name transcription.

Detailed explanation-2: -Transcription, as related to genomics, is the process of making an RNA copy of a gene’s DNA sequence. This copy, called messenger RNA (mRNA), carries the gene’s protein information encoded in DNA.

Detailed explanation-3: -The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.

Detailed explanation-4: -The process of synthesizing RNA from the genetic information encoded by DNA is called transcription. The enzymes involved in transcription are called RNA polymerases. Prokaryotes have one type; eukaryotes have three types of nuclear RNA polymerases.

Detailed explanation-5: -A primary transcript is the single-stranded ribonucleic acid (RNA) product synthesized by transcription of DNA, and processed to yield various mature RNA products such as mRNAs, tRNAs, and rRNAs.
